Gripper jaws (38) for bottles are movable between a gripping and a release position. Passage to the release position is controlled by a slide (42) through the action of a ramp (48) and via tenons (44) connected to the slide (42) and sliding in slots (46). The reverse movement is controlled by the same members through the action of a return spring acting on the slide (42). The transmission of movement effected by the systems comprising tenons (44) and slots (46), is irreversible so that the neck (2) of a bottle held between the jaws (38) cannot be disengaged therefrom: a force (F1) applied to the jaws (38) does not enable the slide to be moved in the direction of opening of the jaws (38). Utilization for producing high-speed machines without increasing the clamping force on the objects (bottles) treated.
